Abstract: A fluid level control valve (30) has a base (32) with an aperture (38) formed therein. A cover (52) is slidingly disposed over the aperture (38) and is biased by a thermostatic element (56) in a direction tending to close the aperture. The thermostatic element (56) is an elongated strip having one end captured by tabs projecting from the base, and an opposite end is captured by a bracket formed on the base. The thermostatic element is formed with a V-shaped force imparting portion (58) which is aligned with the cover and the position of the bracket is adjustable to place a selected force on the cover through the thermostatic element (56). The calibrated valve is then fixedly attached to a housing with the aperture aligned with an aperture in the housing.

Abstract: Signal conversion apparatus transforms an input signal having a value falling in one of a plurality of ranges into an output signal whose value varies for each different range. All of the output signal values corresponding to the plurality of ranges form an ordered set. The output signal values in this set are related to one another such that the value of any output signal is equal to the immediately preceding output signal value multiplied by a predetermined factor which is a constant for at least a plurality of consecutive output signal values. Use of such a relationship between output signal values advantageously reduces quantization errors in certain telecommunications applications and can be embodied within analog-to-digital, digital-to-analog and digital-to-digital signal conversion apparatus.

Abstract: A testing circuit interfaces serially with the data path of an embedded memory circuit formed from at least one memory unit having separated data input and output lines and tandem addressing. Part of the testing circuit is a series of two-input multiplexer units which are adapted to be embedded on the same chip as the memory circuit. The outputs of the multiplexer units connect to a respective one of the data input lines of the memory circuit. Excepting the first bit position, a first input of each multiplexer unit is adapted to connect to the data output line of the adjacent bit position in the memory circuit. The second inputs of the multiplexer units are adapted to connect to the data bus of the chip. A further part of the testing circuit is a finite state machine which is adapted to connect to the first input of the multiplexer unit at the first bit position and to the data output line at the last bit position. During testing, the finite state machine actuates the multiplexer units to connect the first inputs, and for each address outputs a series of test bits, shifts those bits through the addressed word by a series of read and write operations, and examines those bits after their passage through the addressed word for defects in the memory circuit at that address. The finite state machine may or may not be embedded on the same chip as the memory circuit.

Abstract: A sampling circuit able to provide slipping samples of a signal at points-on-wave shifted by a desired fraction of a cycle of the sampled signal of frequency F including an arrangement (7, 9) which produces first and second synchronised periodic signals of frequency PF/M and KPFN respectively where K is an integer, P and M are relatively prime plural integers, P is greater than M and 1/N is a desired phase shift between two sets of samples to be produced by the circuit expressed as a fraction of a cycle of a sampled signal. A first sampling circuit (1) utilises the first periodic signal to control sampling of a signal (I) at the frequency of the first periodic signal and a second sampling circuit (3) utilises every KPth cycle of the second periodic signal before or after a sampling effected by the first sampling circuit to control sampling of a signal (V) at the frequency of the first periodic signal at points-on-wave phase shifted with respect to the points-on-wave sampled by the first sampling circuit. The circuit can be used for instance in reactive energy measuring devices.

Abstract: The activation of glycerol ester hydrolases, toward triglyceride oils, is correlated to the molar ratio of total triglyceride to surfactant concentrations in the test solution. This ratio dependency, when considered in laundry compositions, allows for predictable and improved utilization of these enzymes in the hydrolysis of triglyceride stains. A particularly preferred enzyme for this use is isolatable from  Pseudomonas putida  ATCC 53552. This enzyme, or hydrolase, has sufficient hydrolysis activity in a laundering solution to hydrolyze at least about 5 wt. % of total triglyceride stains in a laundering solution within about 15 minutes at about 25°C.

Abstract: A computer system and process efficiently provides resource recovery for a failure during a commit procedure. An application is run on a processor and requests a work operation involving a resource such as a protected conversation with another application in a different real machine. A commit procedure is begun for the work request, and if the commit procedure fails before completion, the following steps are taken to optimize the use of one or both of the applications. At some time after the commit procedure fails, a return code is sent to at least the application that initiated the commit indicating the result of the application commit order and that the application can continue to run and does not have to wait for resynchronization (recovery). Then, while the initiating application continues to run and do other useful work, resynchronization is implemented in parallel, asynchronously.
